Introduction of flat panel solar water heater

2021/06/21 11:04

Flat-plate solar water heaters are also called solar panel water heaters. They are composed of a collector plate and a water tank. The installation position is not limited. It can be installed on walls, roofs, etc. After installation, there is no sense of conflict with the body of the building, and it can be installed well. Blend into the environment without being obtrusive. Flat-plate solar water heaters have the characteristics of high heat recovery, easy to use, energy saving, fast, safe and reliable, and are mostly used in villa areas or small high-rise residential areas. The flat panel solar water heater is divided into two parts in structure. The necessary components are heat absorption plate, cover plate, insulation layer, shell, hot water storage tank, double-layer inner tank, expansion tank, built-in coil and controller. The heat-absorbing plate is also called the heat-absorbing core plate, which is a kind of component that can absorb solar radiation energy and transfer heat to water; the cover plate is on the surface of the heat-absorbing plate, so that the energy entered is higher than the energy dissipated, which improves the heat-absorbing plate. The function of the thermal insulation layer is to reduce the heat dissipation of the collector to the surrounding environment and improve the thermal efficiency of the collector; the shell is a combination of heat absorbing plate, cover plate, and thermal insulation material, which has a certain degree of rigidity and strength, and is convenient Install and protect internal components. Commonly used shell materials include steel plates, aluminum materials, plastics, etc.; the above-mentioned heat-absorbing plates, cover plates, insulation layers and outer shells are part of the solar panel. In addition, it is composed of heat storage cylinder, inner wall of heat storage cylinder, inner wall of expansion tank, pumping station, built-in coil and controller, etc., used for heat storage cylinder and solar panel to convert energy, and can easily adjust heat cylinder and heat collection The temperature of the device. The difference or type of flat-plate solar water heaters is reflected in the heat-absorbing plate. Commonly available in the market are tube sheet heat-absorbing plate, wing tube heat-absorbing plate, snake tube heat-absorbing plate, flat box heat-absorbing plate, round tube heat-absorbing plate and heat pipe heat-absorbing plate. Different types of heat-absorbing plates have great differences in welding technology, material selection, heat absorption rate and water quality. As for the capacity of the water tank and the size of the solar panels, they belong to the product specifications.
